Why I spend so much time testing payment apps

I test payment apps across LATAM to understand what feels intuitive, what creates friction, and what users quietly tolerate.

A lot of payment products look good in screenshots but feel very different once you actually try to fund them, use them, or rely on them daily.

I've spent the last six years inside Web3 wallets, infra and payments, enabling card programs, interviewing stablecoin teams, and obsessively testing every consumer fintech app

I'm based out of Buenos Aires. I spend most of my time studying onchain payments, onboarding UX, stablecoin products, and how fintech behavior changes market-by-market across the region

This site is where I document product observations, review fintech apps, and work with teams building payment products. If you're building in fintech and stablecoins banking products in LATAM, you'll probably find something useful here.
